Yes, if you have a char (1byte) pointer and you ++, you'll get one byte
further. If you have a short (2byte) you'll get two bytes further in
memory. If you have a long (4byte) pointer, you'll get 4 bytes further
in memory if you ++.
It is simular to dealing with arrays (looking at the memory layout)
If you have an array of structs and need to get to the next struct in
the array then you will need to look sizeof(struct) further in memory to
find the next item in the array.
